Breast reconstruction after mastectomy: A ten-year analysis of trends and immediate postoperative outcomes

Systematic Review of Breast-Q: A Tool to Evaluate Post-Mastectomy Breast Reconstruction

Purpose

The aim of this systematic review is to update and synthesize new evidence on BREAST-Q questionnaire’s ability to reflect patient-reported outcomes in women who have undergone breast reconstruction surgery (BRS) following mastectomy.

Methods

PubMed, Science Direct, Google Scholar, Cochrane CENTRAL, and Clincaltrial.gov were searched for relevant studies from January 2009 to September 2021. Any interventional or observational studies that used BREAST-Q to assess patient-reported outcomes in the assessment of BRS following mastectomy were included.

Results

A total of 42 studies were eligible for inclusion in the review. Three were randomized controlled trials and 39 were observational studies. Compared with pre-operative scores, there was an improvement in all BREAST-Q outcome domains following BRS including ‘satisfaction with breasts’, “satisfaction with outcome” “psychosocial”, “physical”, and “sexual wellbeing”. Sexual well-being had the lowest BREAST-Q score both pre-and post-operatively (37.8–80.0 and 39.0–78.0, respectively). Autologous BRS reports higher satisfaction and overall wellbeing compared to implant-based BRS. BREAST-Q has a higher and narrow internal consistency of 0.81 to 0.96 compared with other patient-reported outcome measures (PROMs; EORTC-QLQ, FACT-B, BR-23, BCTOS). The BREAST-Q questionnaire is the only PROM which allows patients to reflect on their care, surgical outcomes, and satisfaction collectively.

Conclusion

This review highlights the fact that BREAST-Q can effectively and reliably measure satisfaction and wellbeing of breast cancer patients after BRS. Comparatively, sexual wellbeing shows poorer outcomes following BRS and more longitudinal studies are necessary to understand the basis for these findings. Compared to other PROMs, BREAST-Q is reliable and specific to breast cancer surgery. Overall, BREAST-Q can help clinicians improve their quality of service, understand patient experiences, and may be used as an auditing tool for surgical outcomes.

Factors Associated With Increased Complications in Patients With BRCA Gene Mutations Undergoing Reconstructive Breast Surgery

Reconstructive breast surgery after bilateral prophylactic mastectomy in patients who carry a mutation of the breast cancer (BRCA) gene has been increasing. Undergoing risk-reducing breast surgery can be of great benefit to young patients who have a high risk of developing breast cancer. There is little available evidence about the rate of complications in these patients and which factors are related to increased complications. The objective of this study was to identify predictors of complications in BRCA gene mutation carriers who underwent reconstructive breast surgery. A single-center, retrospective cohort study was conducted that included all patients with a mutation of the BRCA gene who underwent a breast reconstructive procedure, either immediate or delayed, between January 2013 and March 2019 and received a minimum of 6 months' follow-up. The results of our study showed that smoking is the most important modifiable risk factor associated with an increased complication rate for reconstructive breast surgery in patients with BRCA gene mutation. Smoking cessation will reduce the patient's risk for postoperative complications by 50%; therefore, it should be encouraged in all surgical patients and enforced in patients undergoing prophylactic procedures.

Long-term outcomes of breast reconstruction and the need for revision surgery

BACKGROUND

Breast reconstruction (BR) often forms part of a patient's breast cancer journey. Revision surgery may be required to maintain the integrity of a BR, although this is not commonly reported in the literature. Different reconstructive methods may have differing requirements for revision. It is important for patients and surgeons to understand the factors leading to the need for revision surgery.

METHODS

This retrospective cohort study analyses BRs performed by oncoplastic breast surgeons in public and private settings between 2005 and 2014, with follow-up until December 2018. Surgical and patient factors were examined, including types of BR, complications and reasons for revision surgery.

RESULTS

A total of 390 women with 540 reconstructions were included, with a median follow-up of 61 months. Twenty-eight percent (151/540) of reconstructions required at least one revision operation. Overall, implant-based reconstructions (direct-to-implant [DTI] and two-stage expander-implant) had a higher revision rate compared to pedicled flap reconstructions (odds ratio 1.91, 95% confidence interval 1.08, 3.38). DTI reconstructions had the highest odds, and pedicled flap without implants the lowest odds of requiring revision. Post-reconstruction radiotherapy increased the chance of revision surgery, while pre-reconstruction radiotherapy did not. Odds of revision were higher in implant-based reconstructions compared to pedicled flap reconstructions that had radiotherapy. Other factors increasing the rates of revision surgery were being a current smoker and post-operative infection.

CONCLUSION

Almost one-third of reconstructive patients require revision surgery. Autologous pedicled flap reconstructions have lower rates of revision compared to implant-based reconstructions. Radiotherapy increases the need for revision surgery, particularly in implant-based reconstructions.

The Association of Overall Annual Hospital Volume and Perioperative Outcomes following Free Flap Breast Reconstruction

BACKGROUND

Hospital volume has been correlated with improved outcomes in oncologic care and complex surgical procedures. The authors sought to determine the relationship between overall annual hospital volume and perioperative outcomes following free flap breast reconstruction.

METHODS

Free flap breast reconstruction patients (n = 7991) were identified at 1907 centers using the Healthcare Cost and Utilization Project National Inpatient Sample database. Logistic regression characterized the association of hospital volume (total discharges per year) with systemic, surgical, and microsurgical complications. Patients were categorized as being treated at low- versus high-volume hospitals based on identified threshold volumes, and the association with the incidence of complications was estimated.

RESULTS

Initially, restricted cubic spline analysis suggested potential threshold volumes of 13,018 (95 percent CI, 7468 to 14,512) and 7091 (95 percent CI, 5396 to 9918) discharges per year, at which the risk for developing systemic and microsurgical complications may change, respectively. However, further patient-level evaluation of treatment at low- versus high-volume hospitals demonstrated that hospital volume did not predict the risk of developing perioperative systemic (OR, 1.28; 95 percent CI, 0.75 to 2.18; p = 0.36) or microsurgical complications (OR, 1.06; 95 percent CI, 0.78 to 1.44; p = 0.73).

CONCLUSIONS

Perioperative complications after free flap breast reconstruction did not differ between patients treated at low- versus high-volume hospitals after in-depth multiprong analysis. Patient outcomes are more likely associated with surgeon and programmatic experience. Overall annual hospital volume should not serve as a proxy for high-quality breast free flap care. .

Optimal reconstructive strategies in the setting of post-mastectomy radiotherapy - A systematic review and network meta-analysis

BACKGROUND

A third of breast cancer patients require mastectomy. In some high-risk cases postmastectomy radiotherapy (PMRT) is indicated, threatening reconstructive complications. Several PMRT and reconstruction combinations are used. Autologous flap (AF) reconstruction may be immediate (AF→PMRT), delayed-immediate with tissue expander (TE [TE→PMRT→AF]) or delayed (PMRT→AF). Implant-based breast reconstruction (IBBR) includes immediate TE followed by PMRT and conversion to permanent implant (PI [TE→PMRT→PI]), delayed TE insertion (PMRT→TE→PI), and prosthetic implant conversion prior to PMRT (TE→PI→PMRT).

AIM

Perform a network metanalysis (NMA) assessing optimal sequencing of PMRT and reconstructive type.

METHODS

A systematic review and NMA was performed according to PRISMA-NMA guidelines. NMA was conducted using R packages netmeta and Shiny.

RESULTS

16 studies from 4182 identified, involving 2322 reconstructions over three decades, met predefined inclusion criteria. Studies demonstrated moderate heterogeneity. Multiple comparisons combining direct and indirect evidence established AF-PMRT as the optimal approach to avoid reconstructive failure, compared with IBBR strategies (versus PMRT→TE→PI; OR [odds ratio] 0.10, CrI [95% credible interval] 0.02 to 0.55; versus TE→PMRT→PI; OR 0.13, CrI 0.02 to 0.75; versus TE→PI→PMRT OR 0.24, CrI 0.05 to 1.05). PMRT→AF best avoided infection, demonstrating significant improvement versus PMRT→TE→PI alone (OR 0.12, CrI 0.02 to 0.88). Subgroup analysis of IBBR found TE→PI→PMRT reduced failure rates (OR 0.35, CrI 0.15-0.81) compared to other IBBR strategies but increased capsular contracture.

CONCLUSION

Immediate AF reconstruction is associated with reduced failure in the setting of PMRT. However, optimal reconstructive strategy depends on patient, surgeon and institutional factors. If IBBR is chosen, complication rates decrease if performed prior to PMRT.

A Study on Breast Reconstruction in a Developing Country: A Comprehensive Evaluation of the Techniques and Oncologic Outcomes

BACKGROUND

Breast cancer, with an incidence of 33.2 per 100,000 in Iranian population, is considered as the most common cancer in Iranian women. Nowadays, with the increasing survival rates, breast reconstruction has been integrated into surgical techniques of breast cancer treatment. The aim of this study was to evaluate the current status of breast reconstruction in Iranian population.

PATIENTS AND METHODS

This retrospective study was conducted in Imam Hospital between January 2008 and June 2018. All the patients underwent breast reconstruction surgery. The trend of reconstruction and complication rates were 2 major outcomes. Logistic regression model was used to predict complications. Student t test was used to compare means.

RESULTS

Fifty-five patients underwent 60 autologous breast reconstruction surgeries and 152 patients underwent 193 prosthesis-based reconstruction surgeries. Most of cases were invasive ductal carcinoma ± ductal carcinoma in situ (126 cases, 68%). Among 253 surgeries in 207 patients, 98 cases (38.7%) were 2-stage implant, 91 (36.0%) were 1-stage implant, 3 (1.2%) were acellular dermal matrix + prosthesis, 31 (12.2%) were pedicled transverse rectus abdominis myocutaneous flap, 25 (9.8%) were latissimus dorsi flap ± prosthesis, and 4 (15.8%) were latissimus dorsi flap. Among prosthesis-based reconstructions, chemotherapy could predict the occurrence of complications (odds ratio, 2.87; 95% CI, 1.07-7.68), whereas none of these factors could predict the occurrence of complications in autologous reconstructions. The most prevalent complication was seroma formation (48.5% of all complications). Overall complication rates (including major and minor) were higher among autologous reconstructions compared with prosthesis-based reconstructions (45.8% and 21.1%, respectively, P < 0.001).

CONCLUSIONS

The trend of breast reconstruction is changing in Islamic Republic of Iran as a developing country. Implant-based reconstruction has surpassed autologous reconstructions in recent years. In terms of complications, we observed higher rates among autologous reconstructions.

Oncoplastic breast surgery: A guide to good practice

Oncoplastic Breast Surgery has become standard of care in the management of Breast Cancer patients. These guidelines written by an Expert Advisory Group; convened by the Association of Breast Surgery (ABS) and the British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS), are designed to provide all members of the breast cancer multidisciplinary team (MDT) with guidance on the best breast surgical oncoplastic and reconstructive practice at each stage of a patient's journey, based on current evidence. It is hoped they will also be of benefit to the wide range of professionals and service commissioners who are involved in this area of clinical practice.

Does Prior Breast Augmentation Affect Outcomes After Mastectomy With Reconstruction? An Analysis of Postoperative Complications and Reoperations

BACKGROUND

The purpose of this study is to evaluate how prior breast augmentation impacts rates of complications and risk for reoperation after mastectomy with concurrent breast reconstruction.

METHODS

Patients undergoing nipple-sparing, skin-sparing, or simple mastectomy with implant-based reconstruction from 2008 to 2018 were identified in a prospective database. Postoperative complications and reoperations were then analyzed comparing patients with prior augmentation to patients without history of previous breast surgery.

RESULTS

A total of 468 patients were identified with a median follow-up of 4 years. Of these, 72 had prior augmentation mammoplasty. These patients underwent nipple-sparing (52, 72%), skin-sparing (15, 21%), or simple (5, 7%) mastectomy with immediate direct-to-implant (46, 61%) or tissue expander (26, 35%) reconstruction. On univariate analysis, this cohort had a lower body mass index (23.3 vs 25.3, P = 0.003), a higher rate of nipple-sparing mastectomy (72% vs 54%, P = 0.01), and a higher prevalence of stage I disease (44% vs 33%, P = 0.04). Differences in age, comorbidities, reconstructive techniques, tumor size, and neoadjuvant/adjuvant therapies were not significant. Overall complication rate between patients with or without prior augmentation did not significantly differ (51% vs 50%, P = 0.83); no significant differences in rates of surgical site infection, hematoma, mastectomy skin flap/wound necrosis, nipple complications, implant loss, or capsular contracture were found. Analysis of reoperations between patients with and without prior augmentation revealed no significant differences in average number of subsequent planned, unplanned, or total reoperations. On multivariate analysis, prior breast augmentation was found to be associated with significantly increased risk for undergoing ≥1 unplanned reoperation (odds ratio, 2.28; 95% confidence interval, 1.28-4.05, P = 0.005).

CONCLUSIONS

Prior augmentation mammoplasty does not significantly affect rates of postoperative complications after mastectomy with concurrent reconstruction. Although prior augmentation does not affect number of subsequent reoperations on average, it does increase the risk of experiencing 1 or more unplanned reoperation after mastectomy with reconstruction.

Prepectoral immediate breast reconstruction with polyurethane foam-coated implants: Feasibility and early results in risk-reducing and therapeutic mastectomies

BACKGROUND

There is a renewed interest for prepectoral reconstruction. We aimed to describe the feasibility and the early complications associated with immediate one-stage direct-to-implant (DTI) reconstruction using prepectoral anatomical polyurethane (PU) foam-coated implants alone, for women with breast cancer or mutation carriers undergoing risk-reducing surgery.

METHODS

We performed a single-center, retrospective review of 50 patients (mean age of 49 years), who underwent skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) and immediate prepectoral PU implant-based reconstruction. All procedures were performed by the same senior operator, from July 2018 to March 2020.

RESULTS

A total of 64 mastectomies (25 SSMs and 39 NSMs) with one-stage prepectoral PU foam-coated implant reconstruction were performed. Out of 50 patients, 6 required surgical revision within 30 days, because of hematoma (2), wound dehiscence (2) infection (1), and full thickness nipple-areolar complex (NAC) necrosis (1). Four patients developed a cutaneous rash with spontaneous resolution. Statistical analysis showed a significant influence of hypothyroidism and previous radiotherapy on the risk of complications. The association with prior radiotherapy (pRT) was not significant using binary logistic regression. When excluding oncological reasons and patient's wish for NAC excision, our decision to perform an NSM was influenced by breast cup size, preoperative measurements, and breast weight.

CONCLUSIONS

Early experience with immediate prepectoral DTI reconstruction with PU-covered implants alone suggests that it is a reliable procedure. Prior breast irradiation does not increase postoperative complication rates in our series. NAC preservation was decided according to preoperative lower breast measurements.

3D Nipple-Areolar Tattoo: It's Technique, Outcomes, and Utilization

BACKGROUND

Three-dimensional (3D) nipple-areolar tattoo is a novel approach to nipple-areolar complex reconstruction for which little data exist. Our aim was to evaluate 3D nipple-areolar tattoo outcomes and investigate if patient factors, payer status, surgeries, or therapies affect tattoo utilization.

METHODS

Patients pursuing skin-sparing (SSM) or attempted nipple-sparing mastectomy (NSM) with breast reconstruction from 2008 to 2019 were reviewed. Outcomes included frequency of 3D tattoo, post-procedure complications (infections, or other local adverse sequelae), and rates, indications, and timing of revisions. Patient factors, payer status, surgeries, and adjuvant therapies underwent univariate analysis comparing rates of 3D tattoo and revisions.

RESULTS

A total of 191 patients were identified; median follow-up was 4 years. The majority of patients were white (165, 86%), married (146, 76%), and post-menopausal (97, 51%), with private insurance (156, 81%). Surgeries included SSM (172, 90%) or attempted NSM (19, 10%) with implant (154, 81%) or autologous reconstruction (37, 19%). Sixty-two patients (32%) underwent 3D nipple-areolar tattooing. No post-procedure complications occurred. After tattooing, 20 patients (32%) pursued revisions, the majority due to color fading (12, 60%). Average time from tattoo to completion of revisions was 5.6 months. Patients undergoing autologous reconstruction had a higher rate of 3D tattooing (p < 0.001). Adjuvant radiation led to a higher rate of revisions (p = 0.02). Patient factors, payer status, index mastectomy, and chemotherapy did not significantly affect rates of 3D tattooing or revisions.

CONCLUSIONS

3D nipple-areolar tattoo utilization is likely unaffected by age, marriage, menopause, or payer status. Radiotherapy and color fading can lead to more revisions.

A look at racial and socioeconomic disparities in post-mastectomy breast reconstruction at a midwestern academic hospital

Purpose of this study was to assess likelihood of undergoing breast reconstruction based on race, socioeconomic status, insurance, and distance from the hospital. Patients with public insurance were less likely to undergo reconstruction than patients with private insurance (OR = 2.99, p < 0.001). White patients were more likely to undergo reconstruction (OR = 0.62, p = 0.02). Patients who lived 10-20 miles and 20-40 miles from UCMC were more likely to undergo reconstruction (OR = 1.93, p = 0.01; OR = 3.06, p < 0.001). White patients and patients with private insurance are disproportionately undergoing breast reconstruction after mastectomy.

Surgical Complications of Skin-Sparing Mastectomy and Immediate Implant-Based Breast Reconstruction in Women Concurrently Treated With Adjuvant Chemotherapy for Breast Cancer

BACKGROUND AND AIM

To date, studies on adjuvant chemotherapy as a risk factor for the surgical outcome of combined mastectomy and breast reconstruction were hampered by the inclusion of mixed reconstructive cohorts of both delayed and immediate timing and of both autologous and implant-based techniques. Consequently, there is a paucity of data on the impact of adjuvant chemotherapy on surgical complication rates after combined skin-sparing mastectomy and immediate implant-based breast reconstruction.

METHODOLOGY

We compared the postoperative complications that occurred within 16 weeks after this combined procedure in 131 women (139 breasts) treated with adjuvant chemotherapy with those in a control group of 491 women (517 breasts) not receiving any adjuvant therapy within 16 weeks.

RESULTS

In line with the clinically indicated selection of women to undergo adjuvant chemotherapy, the interventional group differed significantly from the control group in 7 of the 12 patient- and procedure-related characteristics. The prevalence of minor complications (13.7% and 12.4%, respectively, P = 0.68) and major complications (31.7% and 29.4%, respectively, P = 0.60) did not differ significantly between the interventional group and the controls. The fraction of breasts that needed unscheduled surgery (0.29 and 0.24, respectively, P = 0.20), the fraction of total number of interventions (0.34 and 0.33, respectively, P = 0.24), and the fraction of implants lost (0.72 and 0.67, respectively, P = 0.86) did not differ significantly between both groups. The onset of chemotherapy, furthermore, seemed not to influence the occurrence or severity of complications.

CONCLUSIONS

Like other women who have to undergo mastectomy, women who need to undergo adjuvant chemotherapy can potentially benefit from combined skin-sparing mastectomy and immediate implant-based breast reconstruction.

Does chemotherapy or radiotherapy affect the postoperative complication in breast cancer patients who underwent immediate breast reconstruction with tissue expander?

BACKGROUND

Immediate breast reconstruction with tissue expander in breast cancer patients who were expected to receive adjuvant therapy, such as chemotherapy or radiotherapy, has been a topic of debate. Postoperative complications from tissue expander procedures can delay the timing of adjuvant treatment and subsequently increase the probability of recurrence. The purpose of this study was to identify the impact of chemotherapy and radiotherapy on postoperative complications in patients who underwent immediate reconstruction (IR) using tissue expander.

METHODS

We conducted a retrospective study of 1081 breast cancer patients who underwent mastectomy and IR using tissue expander insertion between 2012 and 2017 in Samsung Medical Center. The patients were divided into two groups based on complications (complication group vs. no complication group). Complication group was regarded to have surgical removal or conservative treatment based on clinical findings such as infection, capsular contracture, seroma, hematoma, rupture, malposition, tissue viability, or cosmetic problem. The complication group had 59 patients (5.5%) and the no complication group had 1022 patients (94.5%).

RESULTS

In univariate analysis, adjuvant radiotherapy and adjuvant chemotherapy were significantly associated with postoperative complications. In multivariate analysis, however, only higher pathologic N stage was significantly associated with postoperative complications (p < 0.001). Chemotherapy (p = 0.775) or radiotherapy (p = 0.825) were not risk factors for postoperative complications.

CONCLUSIONS

IR with tissue expander after mastectomy may be a treatment option even when the patients are expected to receive adjuvant chemotherapy or radiotherapy. These results will aid patients who are concerned about the complications of IR caused by chemotherapy or radiotherapy determine whether or not to have IR.

TRIAL REGISTRATION

Multi-center investigation of breast reconstruction after mastectomy from Chinese Society of Breast Surgery: A survey based on 31 tertiary hospitals (CSBrS-004)

Objective

Multi-center data on the current status and trends of breast reconstruction after mastectomy in China are lacking. Herein, we conducted a cross-sectional survey to investigate the current clinical practice pattern of postmastectomy breast reconstruction among Chinese female patients with breast cancer.

Methods

A standardized questionnaire used to collect information on breast reconstruction among females diagnosed with breast cancer was distributed by 31 members of the Chinese Society of Breast Surgery between January 1, 2018 and December 31, 2018. Information was collected on tumor characteristics, treatment, mesh application, nipple-areola complex (NAC) preservation, postoperative complications, bilateral reconstruction, patient satisfaction and local recurrence. The overall rate of breast reconstruction was assessed, and the characteristics were compared across patient groups with different reconstruction approaches.

Results

A total of 1,554 patients underwent breast reconstruction after total mastectomy, with a reconstruction rate of 9.6%. Among them, 1,190 were implant-based, and 262 underwent autologous reconstructions, while 102 cases underwent a combination of both. Patients who underwent implant-based reconstruction were younger than those who received autologous reconstruction (40.1±4.6 vs. 45.0±5.9, P=0.004). Compared to patients with autologous reconstruction, mesh application (25.5% vs. 6.5%), NAC preservation (51.8% vs. 40.5%) and reconstruction failure (1.8% vs. 0) were more frequently reported among those with implant-based reconstruction. There was no significant difference in general satisfaction across three reconstruction approaches, though patients with autologous reconstruction reported the highest aesthetic satisfaction among the three groups (P=0.044).

Conclusions

Implant-based breast reconstruction remains the dominant choice among patients, while autologous reconstruction was associated with higher aesthetic satisfaction. Our multi-center investigation based on the findings of the tertiary hospitals of Chinese Society of Breast Surgery may guide a future series of clinical studies on breast reconstruction in China.

Effect of contralateral augmentation on postoperative complications after the second stage of tissue expander/implant breast reconstruction

Background

Contralateral augmentation mammoplasty in implant-based reconstruction could potentially lead to deterioration of the thickness of the mastectomy skin flap and increase postoperative complications of the reconstructed breast. We compared the complication rates of the reconstructed breast in the augmentation and no-augmentation groups among patients undergoing tissue expander/implant breast reconstruction.

Methods

Patients who underwent mastectomy followed by tissue expander/implant breast reconstruction between February 2010 and April 2018 were retrospectively reviewed. The primary outcome measures were complications and the need for a revision operation. The augmentation and no-augmentation groups underwent propensity score-matched analysis and the matched cases underwent multivariable logistic regression analysis.

Results

From the 234 patients in the augmentation group and 517 patients in the no-augmentation group, 200 propensity score-matched pairs were obtained. Analysis of the matched pairs revealed that the augmentation group as compared to the no-augmentation group showed a significantly higher overall complication rate (13.5 percent versus 6.5 percent; P=0.025) and revision operation rate (9.0 percent versus 3.0 percent; P=0.019). Multivariable conditional logistic regression analyses of the matched cases revealed that contralateral augmentation (odds ratio, 3.457; 95% confidence interval, 1.039-11.498; P=0.043) was associated with increased odds for a revision operation of the reconstructed breast.

Conclusions

This study investigated the postoperative complications of the reconstructed breast associated with contralateral augmentation mammoplasty in patients who underwent mastectomy followed by tissue expander/implant breast reconstruction. The augmentation group had a higher revision operation rate than did the no-augmentation group. A clinical evaluation of the risks and benefits of contralateral augmentation and preoperative counseling may be indicated for patients who are undergoing implant-based breast reconstruction and are candidates for contralateral augmentation mammoplasty.

Concurrent Prophylactic Mastectomy, Immediate Reconstruction, and Salpingo-Oophorectomy in High-Risk Patients: A Case Series

Purpose

There are limited data on coordinated breast and gynecological risk-reduction surgery for high-risk patients in Canada. Therefore, this study aims to evaluate the patient demographics, surgical details, and outcomes of prophylactic mastectomy (PM) with immediate reconstruction and bilateral salpingo-oophorectomy (BSO) in high-risk patients.

Methods

We conducted a retrospective chart review at an academic center of patients who concurrently underwent PM with immediate reconstruction and laparoscopic BSO over a 7-year period (March 2010-February 2017) were identified.

Results

A total of 16 patients underwent PM with immediate reconstruction and concurrent BSO. The mean age at the time of surgery was 46.2 ± 6.6 years. Thirteen (81%) patients were carriers of the BRCA1 or BRCA2 mutation. Two patients had prophylactic surgical therapy for BRCA1 mutation and 14 (87.5%) patients had prior oncological treatment. The most common type of procedures performed were skin-sparing, nipple-sparing mastectomy (56.2%) and reconstruction with acellular dermal matrix and implants (43.8%). All patients underwent laparoscopic BSO. The average combined case time was 282.5 ± 81.3 minutes with an average postoperative hospital stay of 1.3 ± 0.5 days. Six (37.5%) patients presented with 30-day postoperative complications, with higher rates in the alloplastic group. There were no gynecological complications.

Conclusions

In conclusion, our results demonstrate that a combined multidisciplinary surgical approach did not increase length of stay or 30-day complication rates. Furthermore, concurrent risk-reducing strategies are an effective option for patients at high risk of breast or ovarian cancer.

2020 special issue: Twenty years of breast reconstruction: Past, present, and future

Breast reconstruction has evolved in the last 25 years to provide women with better autologous and implant-based options. The general trends of breast reconstruction have shifted to skin and nipple-areolar complex preservation, resulting in improved aesthetics and patient satisfaction. Autologous reconstruction has made a dramatic movement toward microsurgical reconstruction by free tissue transfer and has addressed lymphedema and breast sensation. Using the patient's own tissues, several aesthetic refinements have led to optimizing the cosmetic appearance of the reconstructed breast. Implant-based reconstruction has improved with the invention of form-stable silicone implants, acellular dermal matrix, and fat grafting. These positive trends will continue into the future. We hope that all women with a diagnosis of breast cancer will have the option of a consultation with a reconstructive plastic surgeon, ideally prior to undergoing resective surgery, to ensure they are aware of all reconstructive options to maximize their reconstructive result.

Cost-effectiveness Analysis of Abdominal-based Autogenous Tissue and Tissue-expander Implant following Mastectomy

Patients who had undergone both autologous abdominal tissue (AAT) and tissue expander and implant (TE/I) breast reconstruction reported satisfaction with their reconstruction. While aesthetics and quality of life are important, the cost associated with these procedures must also be considered when choosing one method over the other. The objective of this study was to determine whether AAT-based breast reconstruction is cost-effective compared with 2-stage TE/I reconstruction at a 12-month follow-up.

Magnitude and dosimetric impact of inter-fractional positional variations of the metal port of tissue expanders in postmastectomy patients treated with radiation

BACKGROUND AND PURPOSE

Postmastectomy breast reconstruction involves the insertion of a temporary tissue expander, which contains a metal injection port. The purpose of this study was to determine the magnitude and dosimetric impact of the inter-fractional positional variations of the port for patients treated with radiation.

MATERIALS AND METHODS

For nine breast cases treated on Tomotherapy, the deviation of the port in the daily MVCT from its reference position was measured in the three cardinal directions. The dosimetric effects of the measured errors were evaluated for two classes of error: Internal Port Error (IPE) and Patient Registration Error (PRE). For each class, dose accumulation was done for daily measured errors and a systematic error.

RESULTS

Inter-fractional positional errors of the port were small, with 87% of the deviations below 5 mm, but errors larger than 1.5 cm were observed. The cumulative effect of the daily measured and systematic IPE decreased target coverage by as much as 2.8% and 3.5%, respectively. The cumulative effect of the daily measured PRE decreased target coverage by an average of 3.5%. The cumulative effect of a systematic PRE significantly decreased target coverage by an average of 16%.

CONCLUSION

The presence of IPE over the course of treatment had minimal clinical impact while PRE had a greater impact on clinically-relevant regions. The robustness of treatment delivery can be improved by assigning the port its appropriate density during planning despite contouring uncertainties due to metal artefacts, and by prioritizing anatomical alignment over port alignment during daily registration.

The Blue-Blood Porcine Chest Wall: A Novel Microsurgery Training Simulator for Internal Mammary Vessel Dissection and Anastomosis

BACKGROUND

 Preparation of the internal mammary artery (IMA) is a critical step in autologous breast reconstruction. Intraoperatively, there is limited opportunity for residents to practice this skill. Porcine models provide highly realistic simulation for vascular surgery; however, use of live laboratory pigs is expensive, inconvenient, and offers limited opportunity for repetitive training. We aimed to develop an inexpensive and effective training model for IMA preparation. This article describes creation of a novel microsurgical model using cadaveric chest walls of Wisconsin Miniature Swine embedded in a modified mannequin thorax and augmented with a blue-blood perfusion system.

METHODS

 Anatomic comparison: five porcine chest walls were dissected, and various anatomic measurements were made for anatomic comparison to existing human data in the literature. Model assembly: the chest wall is prepared by cannulating the proximal and distal ends of the internal mammary vessels with angiocatheters, which are then connected to the blue-blood perfusion system. The model is assembled in four layers including: (1) a mannequin thorax with a window removed to expose the first to fourth intercostal spaces, bilaterally, (2) a layer of foam simulating fat, (3) the perfused pig chest wall, and (4) a second mannequin shell placed posteriorly for support.

RESULTS

 The porcine chest walls are similar to humans with regards to vessel size and location. This model can be assembled quickly, with a one-time approximate cost of $55.00, and allows for six training sessions per specimen. The model allows residents to practice the key steps of IMA preparation including dissection, elevation of perichondria, and vascular anastomosis while working at a depth that closely simulates the human thorax. Continuous blue-blood perfusion provides immediate feedback on anastomosis quality.

CONCLUSION

 Overall, this novel model can provide inexpensive and realistic simulation of internal mammary vessel preparation and anastomosis.

Exploring the Effect of Post-mastectomy complications on 5-year survival

BACKGROUND

Ramifications of postoperative complications on long-term survival after mastectomy are uncertain.

METHODS

Overall complications (Clavien-Dindo Grades I-IIIB) and wound complications were analyzed using the Kaplan-Meier method for impact on 5-year overall (OS) and disease-free survival (DFS).

RESULTS

A total of 378 patients underwent mastectomy alone (157, 41%) or mastectomy with reconstruction (221, 59%) for Stage I-III disease with a median follow-up of 5 years. Postoperative complications occurred in 186 patients (49%), requiring non-surgical (I/II = 83, 22%) or surgical (IIIa/IIIb = 103, 27%) management. Wound complications occurred in 140 patients (37%). Reconstruction was associated with a higher rate of complication (P < 0.001). Postoperative complications after mastectomy (with or without reconstruction) did not significantly affect OS or DFS. Wound complications also showed no significant effect on OS or DFS following mastectomy alone, or mastectomy with reconstruction.

CONCLUSIONS

Postoperative complications after mastectomy, with or without reconstruction, bear no significant impact on 5-year survival.

The effect of sarcopenia on perioperative complications in abdominally based free-flap breast reconstruction

PURPOSE

The identification of patient-specific risk factors, which predict morbidity following abdominally based microvascular breast reconstruction is difficult. Sarcopenia is a proxy for patient frailty and is an independent predictor of complications in a myriad of surgical disciplines. We predict that sarcopenic patients will be at higher risk for surgical complications following abdominally based microvascular breast reconstruction.

METHODS

A retrospective study of all patients who underwent delayed abdominally based autologous breast reconstruction following postmastectomy radiation therapy from 2007 to 2013 at a single institution was conducted. Univariate and multiple logistic regression models were used to assess the effect of sarcopenia on postoperative outcomes.

RESULTS

Two hundred and eight patients met the inclusion criteria, of which 30 met criteria for sarcopenia (14.1%). There were no significant differences in demographics between groups. There were no significant differences in minor (36.7% vs 44.4%; P = .43) or major (16.7% vs 25.3%; P = .36) complications between groups as well as hospital length of stay. Multivariable logistic regression demonstrated that a staged reconstruction with the use of a tissue expander was the only consistent variable, which predicted major complications (OR, 2.24; 95% CI, 1.18-4.64; P = .015).

CONCLUSIONS

Sarcopenia does not predispose to minor or major surgical complications in patients who undergo abdominally based microsurgical breast reconstruction.

Optimal breast reconstruction type for patients treated with neoadjuvant chemotherapy, mastectomy followed by radiation therapy

PURPOSE

To explore the optimal type of breast reconstruction and the time interval to postmastectomy radiotherapy (PMRT) associated with lower complications in breast cancer patients receiving neoadjuvant chemotherapy.

METHODS

We reviewed the medical records of 300 patients who received neoadjuvant chemotherapy, mastectomy with breast reconstruction and PMRT at our institution from 2000 to 2017. Reconstruction types included autologous flaps (AR), single-stage-direct-to-implant and two-stages expander/implant (TE/I). The primary endpoint was the rate of reconstruction complications including infection, skin and fat necrosis. Subgroup analysis compared rates of capsular contracture, implant rupture, implant exposure and overall implant failure in single-stage-direct-to-implant to TE/I. The secondary endpoint was identifying the time interval between surgery with immediate implant-based reconstruction and PMRT associated with lower probability of implant failure. Logistic regression models, Kaplan-Meier estimates and Polynomial regression were used to assess endpoints.

RESULTS

The median follow-up was 43.5 months. 29.3%, 28.3% and 42.4% of the cohort had AR, TE/I and single-stage-direct-to-implant D, respectively. The 5-year cumulative incidence rate of complications was 14.0%, 29.7% and 19.4% for AR, TE/I and single-stage-direct-to-implant, respectively (Log rank p = 0.02). Multivariate analysis showed significant association between TE/I and higher risk of infection (OR 8.1, p = 0.009) compared to AR, while single-stage-direct-to-implant and AR were comparable (OR 3.2, p = 0.2). On subgroup analysis, TE/I was significantly associated with higher rates of implant failure. The mean wait time to deliver PMRT after immediate reconstruction with no adjuvant chemotherapy was 8.4 and 10.7 weeks in single-stage-direct-to-implant and TE/I, respectively (p < 0.005). Delivering PMRT after 8 weeks of surgery yielded 10% probability of reconstruction failure in single-stage-direct-to-implant versus 40% in TE/I.

CONCLUSION

In comparison to two stages reconstruction, single-stage-direct-to-implant following neoadjuvant chemotherapy has lower complications and offers timely delivery of PMRT.

Hereditary Gastric and Breast Cancer Syndromes Related to CDH1 Germline Mutation: A Multidisciplinary Clinical Review

E-cadherin (CDH1 gene) germline mutations are associated with the development of diffuse gastric cancer in the context of the so-called hereditary diffuse gastric syndrome, and with an inherited predisposition of lobular breast carcinoma. In 2019, the international gastric cancer linkage consortium revised the clinical criteria and established guidelines for the genetic screening of CDH1 germline syndromes. Nevertheless, the introduction of multigene panel testing in clinical practice has led to an increased identification of E-cadherin mutations in individuals without a positive family history of gastric or breast cancers. This observation motivated us to review and present a novel multidisciplinary clinical approach (nutritional, surgical, and image screening) for single subjects who present germline CDH1 mutations but do not fulfil the classic clinical criteria, namely those identified as-(1) incidental finding and (2) individuals with lobular breast cancer without family history of gastric cancer (GC).

Breast-contour preserving procedures for early-stage breast cancer: a population-based study of the trends, variation in practice and predictive characteristics in Denmark and the Netherlands

PURPOSE

Breast-contour preservation (BCP) is possible for most women treated for early-stage breast cancer. BCP can be defined as primary breast-conserving treatment (BCT), neoadjuvant chemotherapy (NAC) followed by BCT and immediate postmastectomy breast reconstruction (IBR). This study provides insight in current BCP strategies in Denmark and the Netherlands and aims to identify opportunities for improvement within both countries.

METHODS

A total of 92,881 patients with early-stage breast cancer who were operated in Denmark and the Netherlands between 2012 and 2017 were selected from the Danish Breast Cancer Group and the Dutch National Breast Cancer Audit databases. BCP procedures and predictive factors were analyzed within and between both countries.

RESULTS

BCP was achieved in 76.7% (n = 16,355) of the Danish and in 74.5% (n = 53,328) of the Dutch patients. While BCP rate did not change significantly over time in Denmark (p = 0.250), a significant increase in BCP rate from 69.5% in 2012 to 78.5% in 2017 (p < 0.001) was observed in the Netherlands. In both countries, variation in BCP rates between hospitals decreased over time. NAC followed by BCT and postmastectomy IBR was substantially more often used in the Netherlands compared to Denmark, specifically in patients younger than 50 years.

CONCLUSIONS

In more than 75% of all Danish and Dutch patients, surgically treated for early-stage breast cancer, the breast-contour was preserved. The different use of BCP strategies within Denmark and the Netherlands and the differences observed between hospitals in both countries emphasize the need for more (inter)national consensus on treatment modalities.

The Value of Repeated Breast Surgery as a Quality Indicator in Breast Cancer Care

Breast-conserving surgery, a major achievement in surgical oncology, has allowed an increasing number of breast cancer patients to avoid the mutilation of mastectomy. However, mastectomy still is performed in certain circumstances although breast-conserving surgery would be equally safe. Many reasons, including patients' and surgeons' personal motivations, influence the decision-making process before the final choice between breast preservation and mastectomy. The importance of quality measurement and reporting in medicine is increasingly recognized, and breast surgery is no exception. The substantial variability of re-excision rates for positive surgical margins after a first attempt at breast-conserving surgery suggests that improvement is possible. Therefore, the re-excision rate has been proposed as a quality metric for assessing and comparing the performance of different institutions. Indeed, re-excision rates can be reduced by actionable factors such as accurate preoperative local staging, localization of occult lesions, and intraoperative assessment of the oriented specimen. However, equally important non-actionable risk factors pertaining the biology, detectability, and resectability of the tumor also should be taken into account. Therefore, if the re-excision rate has to be used as a performance indicator of breast surgical care, critical interpretation of results with accurate case-mix adjustment are mandatory, and reasonable targets must be appropriately set so that surgeons treating patients at higher risk of positive margins are not unduly penalized.

The influence of mastectomy and reconstruction on residual upper limb function in breast cancer survivors

PURPOSE

Breast cancer survivorship is common (90% of women survive 5 or more years), but many women are not able to return to full function and well-being after treatment due to functional limitations, persistent pain, and inability to perform daily activities. Since each surgical reconstructive option (e.g., autologous tissue flaps versus implants) can impact shoulder and arm function differently, it is important to understand how shoulder and upper limb strength, mobility, and function are influenced by the type of surgical intervention. Efforts can then focus on prehabiliation strategies to prevent the onset of limitations and on developing rehabilitation protocols that directly target shortcomings.

METHODS

The current paper presents a review summarizing how shoulder and upper limb function may be affected by surgical mastectomy and breast reconstruction.

RESULTS

Mastectomy and breast reconstruction with implants or autologous tissues present different functional outcomes for patients. Each surgical procedure is associated with unique sequelae derived from the tissues and procedures associated with each surgery. Characterizing the specific functional outcomes associated with each surgical approach will promote the development of targeted rehabilitation strategies that can be implemented into a multidisciplinary treatment planning pathway for breast cancer patients.

CONCLUSIONS

Surgical treatments for breast cancer, including mastectomy and breast reconstruction, can have negative effects. Focused efforts are needed to better understand treatment-specific effects so that targeted rehabilitation can be developed to improve patient function, QoL, and ability to return to work and life activities post-breast cancer.

Disparities in Access to Autologous Breast Reconstruction

Background and objectives: This study aimed to determine if age, race, region, insurance, and comorbidities affect the type of breast reconstruction that patients receive. Materials and methods: This analysis used the Florida Inpatient Discharge Dataset from 1 January 2013 to 30 September 2017, which contains deidentified patient-level administrative data from all acute care hospitals in the state of Florida. We included female patients, diagnosed with breast cancer, who underwent mastectomy and a subsequent breast reconstruction. We performed an χ2 test and logistic regression in this analysis. Results: On the multivariable analysis, we found that age, race, patient region, insurance payer, and Elixhauser score were all variables that significantly affected the type of reconstruction that patients received. Our results show that African American (odds ratio (OR): 0.68, 95%CI: 0.58-0.78, p < 0.001) and Hispanic or Latino (OR: 0.82, 95%CI: 0.72-0.93, p = 0.003) patients have significantly lower odds of receiving implant reconstruction when compared to white patients. Patients with Medicare (OR: 1.57, 95%CI: 1.33-1.86, p < 0.001) had significantly higher odds and patients with Medicaid (OR: 0.61, 95%CI: 0.51-0.74, p < 0.001) had significantly lower odds of getting autologous reconstruction when compared to patients with commercial insurance. Conclusions: Our study demonstrated that, in the state of Florida over the past years, variables, such as race, region, insurance, and comorbidities, play an important role in choosing the reconstruction modality. More efforts are needed to eradicate disparities and give all patients, despite their race, insurance payer, or region, equal access to health care.

Physical side-effects following breast reconstructive surgery impact physical activity and function

PURPOSE

To investigate the incidence and severity of physical side-effects experienced by women following breast reconstructive surgery and the effect of these side-effects on physical activity and function.

METHODS

Two hundred and thirty-one Australian women (55 years SD 6.5) who had previously had breast reconstruction surgery retrospectively self-reported the incidence and severity of eight physical side-effects and the perceived effect of these side effects on six physical functions, at three time points after their surgery. The frequency of the combined incidence/severity scores and their impact at the three time points were tabulated and compared using Chi-squared tests. A general linear regression was used to identify characteristics associated with moderate-very high (≥ 5/10) combined incidence/severity scores.

RESULTS

At 6 months following surgery, approximately 50% of respondents reported moderate to very high incidence/severity scores for physical side-effects across multiple body regions, which were perceived to limit their physical function and activity levels. The highest incidence/severity scores were associated with the following: (i) pre-existing physical problems before surgery, (ii) post-operative complications (seroma, infection, necrosis), and (iii) autologous rather than implant-based reconstructions.

CONCLUSION

A large percentage of women reported moderate to severe physical side-effects across multiple body regions following breast reconstructive surgery. These side-effects were perceived to negatively impact both physical function and activity. Early intervention, education and treatment are recommended to alleviate these issues and minimise their negative impact.

Comparing Prepectoral Versus Subpectoral Tissue Expander Placement Outcomes in Delayed-Immediate Autologous Breast Reconstruction

BACKGROUND

Delayed-immediate breast reconstruction has traditionally involved placement of tissue expanders (TE) in the subpectoral (SP) position. Development of acellular dermal matrices has renewed interest in the prepectoral (PP) pocket, which avoids extensive muscle manipulation. We compare complication rates between PP and SP TE placement in autologous delayed-immediate breast reconstruction.

METHODS

A retrospective chart review of patients undergoing autologous, delayed-immediate breast reconstruction at our institution (June 2009 to December 2018) was performed. Demographics, comorbidities, perioperative information, and complication incidence ≤12 months' follow-up were collected from first- and second-stage surgeries. Complications were modeled using univariable and multivariable binary logistic regressions.

RESULTS

A total of 89 patients met the inclusion criteria, and data from 125 breast reconstructions were evaluated. Complication rates following TE placement trended lower in the PP cohort (28.8% vs 37%, P = 0.34). Overall complication rates following autologous reconstruction were significantly lower for PP reconstructions (7.7% vs 23.3%, P = 0.02). Multivariable regression showed TE position (P = 0.01) was a significant predictor of ≥1 complication following autologous reconstruction. Time delay between first- and second-stage surgeries was greater for SP reconstructions (199.7 vs 324.8 days, P < 0.001). Postoperative drains were removed earlier in the PP cohort (8.6 vs 12.0 days, P < 0.001). Mean follow-up time was 331.3 days.

CONCLUSIONS

Prepectoral reconstruction in the delayed-immediate autologous reconstruction patient leads to significantly lower complication rates, shorter duration between first- and second-stage surgeries, and shorter times before removal of breast drains compared with SP reconstructions.

Deconstructing the Reconstruction: Evaluation of Process and Efficiency in Deep Inferior Epigastric Perforator Flaps

BACKGROUND

With advances in technology and technique, the goal of microvascular breast reconstruction has transitioned from flap success to minimizing complications and maximizing aesthetic outcome and efficiency. In an effort to evaluate efficiency, the authors implemented a rigorous process analysis in their practice to evaluate deep inferior epigastric perforator (DIEP) flap breast reconstruction.

METHODS

A prospective implementation of process analysis was instituted on 147 DIEP flaps. The eight critical maneuvers for a DIEP flap are (1) skin to perforator identification, (2) perforator decision making, (3) perforator dissection, (4) pedicle dissection, (5) flap harvest, (6) preparation for microsurgery, (7) venous anastomosis, and (8) arterial anastomosis. Surgeons with variable experiences (faculty, faculty with senior resident/fellow, and supervised chief resident) used these eight steps to perform DIEP flap reconstruction. The outcomes and time of each maneuver were tracked.

RESULTS

The total flap harvest time among the three groups was 54.8 minutes for faculty surgeons, 98.3 minutes for senior resident/fellow working with faculty, and 178.8 minutes for supervised chief resident (p < 0.001). The largest difference was seen in perforator dissection. Increasing the number of perforators resulted in longer flap harvest times. Perforator location did not have an impact on times, but harvesting multiple rows took longer for less experienced surgeons. Body mass index and flap weight did not have an impact on time.

CONCLUSIONS

The authors share their experience using process analysis for DIEP flap reconstruction. They defined eight critical maneuvers to maximize efficiency and safety. By communicating efficient processes and integrating them into the workflow of a given operation, surgeons can continue to improve throughout the arc of their careers.

Do Postoperative Prophylactic Antibiotics Reduce Highly Virulent Infections?: An Analysis of 660 Tissue Expander Breast Reconstructions

BACKGROUND

Many surgeons are reluctant to discontinue prophylactic antibiotics after 24 hours in tissue expander breast reconstruction (TEBR) because of fear of increased risk of surgical site infection (SSI). Currently, there is no consensus regarding antibiotic prophylaxis duration in TEBR. In addition, there remains a lack of research investigating microorganisms involved in SSI across various perioperative antibiotic protocols. The purpose of this study was to examine how 2 different prophylactic antibiotic regimens impacted the bacterial profiles of SSI and rate of implant loss after TEBR.

METHODS

A single-institution retrospective review of immediate TEBRs between 2001 and 2018 was performed. Surgical site infections requiring hospitalization before stage 2 were included. Highly virulent organisms were defined as ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter species). Implant loss was defined as removal of tissue expander without immediate replacement.

RESULTS

Of 660 TEBRs, 85 (12.9%) developed an SSI requiring hospitalization before stage 2. Fifty-six (65.9%) received less than 24 hours of perioperative intravenous antibiotics and oral antibiotics after discharge (group 1), and 29 (34.1%) received less than 24 hours of intravenous antibiotics only (group 2). There was no significant difference in demographics, preoperative chemotherapy/radiation, acellular dermal matrix usage, or treatment of SSI between groups. In group 1, 64% (n = 36) developed culture positive SSIs, compared with 83% (n = 24) in group 2 (P = 0.076). Staphylococcus aureus was the most common bacteria in both groups. Group 2 demonstrated a significantly increased incidence of gram-positive organisms (46.4% vs 72.4%, P = 0.022) and S. aureus (21.4% vs 55.2%, P = 0.002). However, there was no significant difference in overall highly virulent (P = 0.168), gram-negative (P = 0.416), or total isolated organisms (P = 0.192). Implant loss between groups 1 and 2 (62.5% vs 62.1%, P = 0.969) respectively, was nearly identical.

CONCLUSIONS

Our study demonstrates that, despite differences in bacterial profiles between 2 antibiotic protocols, prolonged postoperative antibiotic use did not protect against overall highly virulent infections or implant loss. Antibiotic stewardship guidelines against the overuse of prolonged prophylactic regimens should be considered. Further analysis regarding timing of SSIs and antibiotic treatment is warranted.

A Multimetric Health Literacy Analysis of Autologous Versus Implant-Based Breast Reconstruction

BACKGROUND

Over the past decade, the demand for breast reconstruction has mirrored the rising incidence of breast cancer. Common postoncologic surgical options include autologous and implant-based reconstruction. Patient-directed health information for breast reconstruction can play a critical role in the decision-making process. This study comparatively evaluates the top online resources for autologous versus implant-based reconstruction using a multimetric health literacy analysis.

METHODS

The top 10 websites for autologous and implant-based reconstruction were identified using a Google search. A total of 20 unique links were appraised by 2 independent raters for understandability and actionability using the Patient Education Materials Assessment Tool and cultural sensitivity using the Cultural Sensitivity Assessment Tool. A Cohen κ for interrater reliability was calculated. Mean reading grade level and word complexity were also determined.

RESULTS

Websites for both autologous and implant-based modalities exceeded the recommended sixth- to eighth-grade reading level (12.4 and 12.1, respectively; P = 0.65). Mean understandability scores for each modality were low (60.5 and 62.5, P = 0.65). Autologous-based resources had a lower mean actionability score compared with implant-based materials (19.5 and 24, respectively; P = 0.04). Both reconstructive modalities met the threshold for acceptability for cultural sensitivity (2.79 and 2.58, P = 0.09).

CONCLUSIONS

Our study revealed a chasm between the health literacy needs of the average adult and the quality of both implant-based and autologous breast reconstruction resources. Materials for both modalities were often too complex and failed to include tools to facilitate active decision making, particularly for autologous-based reconstruction. Strategies to improve materials should be patient centered and include simplification of reading grade level, incorporation of clear visual aids, and inclusion of procedural risks to promote patient comprehension, participation, and ultimately health outcomes.

Elective Revisions after Breast Reconstruction: Results from the Mastectomy Reconstruction Outcomes Consortium

BACKGROUND

Rates of breast reconstruction following mastectomy continue to increase. The objective of this study was to determine the frequency of elective revision surgery and the number of procedures required to achieve a stable breast reconstruction 2 years after mastectomy.

METHODS

Women undergoing first-time breast reconstruction after mastectomy were enrolled and followed for 2 years, with completion of reconstruction occurring in 1996. Patients were classified based on the absence or presence of complications. Comparisons within cohorts were performed to determine factors associated with revisions and total procedures. Mixed-effects regression modeling identified factors associated with elective revisions and total operations.

RESULTS

Overall, 1534 patients (76.9 percent) had no complications, among whom 40.2 percent underwent elective revisions. The average number of elective revisions differed by modality (p < 0.001), with abdominally based free autologous reconstruction patients undergoing the greatest number of elective revisions (mean, 0.7). The mean total number of procedures also differed (p < 0.001), with tissue expander/implant reconstruction patients undergoing the greatest total number of procedures (mean, 2.4). Complications occurred in 462 patients (23.1 percent), with 67.1 percent of these patients undergoing elective revisions, which was significantly higher than among patients without complications (p < 0.001). The mean number of procedures again differed by modality (p < 0.001) and followed similar trends, but with an increased mean number of revisions and procedures overall. Mixed-effects regression modeling demonstrated that patients experiencing complications had increased odds of undergoing elective revision procedures (OR, 3.2; p < 0.001).

CONCLUSIONS

Breast reconstruction patients without complications undergo over two procedures on average to achieve satisfactory reconstruction, with 40 percent electing revisions. If a complication occurs, the number of procedures increases.

Closing the Breast Cancer Loop: Barriers and Perceptions of Breast Reconstruction among Rural Women

Background:

Despite policies such as the Women's Health and Cancer Rights Act (WHCRA) and Breast Cancer Patient Education Act, rates for breast reconstruction vary and are especially low for some subpopulations of patients, especially rural women. In order to better understand patient perceptions, qualitative analysis using focus groups is an underutilized tool for obtaining patient perspectives regarding health-related issues and access to care. Our aim was to better understand patient perceptions using qualitative analysis.

Methods:

Three focus groups were held in rural counties within West Virginia in order to better understand patient perceptions, knowledge, and beliefs regarding breast health, breast cancer, access to breast reconstruction, and how to disseminate and educate this patient population regarding their right to accessing breast reconstruction.

Results:

Major themes analyses revealed perceived barriers to care related to lacking care coordination, lack of insurance coverage and other resources, as well as issues related to transportation. Participants consistently discussed avoiding breast screening care due fear and denial in addition to pain. Few patients were aware of their right to accessing breast reconstruction per the WHCRA, and many were concerned about follow-up burden, complications, and general fear related to breast reconstruction. Themes related to dissemination of information to promote the option of breast reconstruction included social media, patient counseling by their referring physician, and other means of intervention in clinics and other points in the care coordination chain.

Conclusions:

Rural women have important, unique viewpoints regarding access to and perceived barriers from obtaining breast reconstruction. Plastic surgeons must work diligently to educate, disseminate, and improve care coordination among this population in order to improve access to breast reconstruction among rural breast cancer patients.

Use of Sentinel Lymph Node Incision for Second Stage Implant-Based Breast Reconstruction After Radiation

BACKGROUND

Staged expander to implant breast reconstruction is associated with a high complication rate when the patient has had postmastectomy radiation. With an increasing number of American women undergoing implant-based breast reconstruction after postmastectomy radiation, surgeons may find themselves operating in a radiated field with synthetic devices. We report the performance characteristics of a novel surgical modification to the second stage expander to implant exchange after adjuvant radiation using a transaxillary approach through a prior sentinel lymph node incision, a site remote from the breast implant pocket.

METHODS

We performed a retrospective review of a prospectively maintained database to evaluate the surgical outcomes of serial patients undergoing second staged expander to implant exchange through the sentinel lymph node incision 6 months or more after completing whole breast radiation. A case matched cohort to age, body mass index, and comorbid status was used to compare outcomes between patients in the group of interest versus a traditional skin sparing incision on the anterior breast mound through the radiated skin envelope. All patients included demonstrated grade 1 or 2 skin changes on the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer Late Radiation Morbidity Scoring Schema for the skin organ system.

RESULTS

Nineteen breasts were reconstructed for 18 women after immediate tissue expander placement and adjuvant whole breast radiation were included in our group of interest. Forty-one case-matched second controls were identified for the comparison group. There were no intraoperative complications. Two postoperative complications were reported for the sentinel lymph node approach group (10.5%) with an average of 9 months of follow-up: 1 operative exploration for hematoma and 1 minor wound requiring recloser in the office. The case matched cohort demonstrated significantly more minor postoperative complications (P = 0.037) with a total complications rate of 41.4%. There were 31.7% of the patients that experienced a minor complication alone, whereas 9.7% of the case-matched cohort experienced a major complication.

CONCLUSIONS

These data support the use of the existing axillary sentinel lymph node access incision for second stage placement of a gel implant after immediate expander and adjuvant radiation therapy. The sentinel lymph node incision approach facilitates layered closure over the breast pocket at a site remote from irradiated tissue, reducing the incidence of postoperative minor complications. Forthcoming long-term data will determine if differences in reported capsular contracture rates can be achieved with a remote transaxillary approach to second stage implant reconstruction after radiation.

Cost Utility of Breast Tissue Expansion using Carbon Dioxide versus Saline: An Analysis of Infection Risk

The AeroForm System, a needle-free, patient-controlled carbon dioxide-filled tissue expander, represents a novel option for tissue expansion in 2-stage breast reconstruction. This technology has previously been found to decrease time to expansion, health-care utilization, and infection rates. The purpose of this study was to determine the economic impact of the reduced infection rate observed with the AeroForm tissue expander as compared with saline tissue expansion.

The Bell Pattern: A Novel Breast Incision Approach to Skin-Reducing Mastectomies

Background

As immediate direct to permanent implant-based breast reconstruction (IBBR) continues to gain in popularity, surgeons seek to apply these techniques to patients with large or ptotic breasts. A new bell pattern skin excision is described and limits major complications in this high-risk population.

Objective

The authors describe a novel skin excision pattern for patients with large or ptotic breasts who desire IBBR and assess its safety. The authors also evaluated the ability of the pattern to account for intraoperative developments.

Methods

This retrospective analysis of a single surgeon’s experience included 17 consecutive patients (31 breasts) with large or ptotic breasts undergoing skin-reducing mastectomy with attempted utilization of the bell pattern approach and IBBR with acellular dermal matrix.

Results

Mean age was 50 years, mean body mass index was 27.4 kg/m², and mean breast specimen weight was 683 g. A bell pattern excision was planned for all breasts preoperatively. Three breasts (10%) required an alternative closure pattern due to intraoperative ischemia (n = 1), or additional oncologic resection (n = 2). The pattern successfully accommodated flap ischemia in 8 (26%) other breasts. After a median follow-up of 5.1 months, the number of bell pattern breasts with major and minor complications was 0 (0%) and 9 (32%), respectively. The most common minor complication was seroma (n = 5, 18%), and minor incision wound (n = 3, 11%). There were no reconstruction failures utilizing the bell pattern.

Conclusion

The bell pattern approach is a safe and adaptable alternative to traditional skin-reducing mastectomy in patients with large or ptotic breasts.

Significance of Infections in Implant Loss After Breast Reconstruction in the Course of Breast Cancer Treatment

The aim of the study was to analyze the reasons for removing implants after breast reconstruction in the course of treatment of breast cancer. The study involved 428 patients, who underwent a total of 648 breast reconstruction procedures using artificial implants. 47 out of 648 cases (7.3%) were identified in which the implant had to be removed. Of the 47 cases, 57.4% had undergone deferred reconstruction, and 42.6% immediate reconstruction; 27.7% had undergone pre-operative chemotherapy and radiotherapy, 27.7% pre-operative chemotherapy, and 2.1% pre-operative radiotherapy; 6.4% were diabetic, 4.3% active smokers, and more than 50.0% had BMI greater than 25 kg/m². In 83.0% of the analyzed cases, the reason for removal of the implant was infection, in 8.5% it was local recurrence of breast cancer, in 4.3% it was damage (leakage) of the implant, and in 2.1% it was post-operative pain. About 87.0% of infections appeared within one year of implantation; however, less than a half developed within 90 days of the reconstructive surgery, and up to 30 days only about 13.0% had appeared. Among the etiological agents of infections were: coagulase-negative Staphylococcus (31.3%), Staphylococcus aureus (18.7%), Enterococcus faecalis (9.4%), Enterobacter cloacae (18.8%), Pseudomonas aeruginosa (12.5%), Acinetobacter lwoffii (3.1%), and other Gram-negative fermenting rods accounted for 6.2%. Infections were the most common reason for removing the implant after breast reconstruction. and occurred most often as late infections (>30 days after surgery). The time of observation for infectious complications should be at least 1 year.

Surgical Site Infection after Breast Surgery: A Retrospective Analysis of 5-Year Postoperative Data from a Single Center in Poland

Background and Objectives: Surgical site infection (SSI) is a significant complication of non-reconstructive and reconstructive breast surgery. This study aimed to assess SSI after breast surgery over five years in a single center in Poland. The microorganisms responsible for SSI and their antibiotic susceptibilities were determined. Materials and Methods: Data from 2129 patients acquired over five years postoperatively by the Department of Surgical Oncology, Medical University of Gdansk in Poland were analyzed. Results: SSI was diagnosed in 132 patients (6.2%) and was an early infection in most cases (65.2%). The incidence of SSI was highest in patients who underwent subcutaneous amputation with simultaneous reconstruction using an artificial prosthesis (14.6%), and breast reconstruction via the transverse rectus abdominis muscle (TRAM) flap method (14.3%). Gram-positive bacteria were responsible for SSI in most cases (72.1%), and these were mainly Staphylococcus strains (53.6%). These strains were 100% susceptible to all beta-lactam antibiotics (except penicillin) but were less susceptible to macrolides and lincosamides. Conclusions: SSI is a serious problem, and attention should be focused on its prevention. Reconstruction using an artificial prosthesis or via the TRAM flap method is connected to increased SSI incidence. Further studies are required to prevent SSI following breast surgery.

The use of Patient Reported Outcome Measures in assessing patient outcomes when comparing autologous to alloplastic breast reconstruction: a systematic review

Breast reconstruction surgery after mastectomy has demonstrated positive psychological benefits, and is reflected in the number of patients undergoing the procedure, rising from 26.94% of patients after mastectomy in 2005, to 43.30% in 2014. Most of this is attributable to implant and expander-based reconstruction, with the rate of free flaps only increasing from 1.25% to 3.96% in this time period. Increasingly, breast cancer patients have higher survival rates. There is now an emphasis on Value Based Health Care (VBHC), which focusses on outcomes, and that can be measured by Patient Reported Outcome Measures (PROMs). To date, there has been no systematic review to analyse PROMs between those undergoing autologous or alloplastic reconstruction, using validated measurement tools, to determine if there is a preferred technique from the patient's perspective. We performed a systematic search on EMBASE, and together with bibliographic linkage, identified 146 articles. After screening and assessment of articles through abstract, and full article appraisal, 13 were identified suitable for inclusion in this systematic review. Using BREAST-Q, satisfaction of breast and psychosocial well-being were rated highly by the autologous group when compared to implant-based reconstruction. Physical well-being was less significant, with the least significant difference noted for sexual well-being. EORTC-QLQ-BR23/C30 PROMs noted similar trends. SF-36 however, noted virtually no difference between the two methods of reconstruction regarding similar PROM quality of life (QoL) domains. From the patient perspective, autologous reconstruction is either equal to or superior to implant-based reconstruction, and should be offered to all patients.

Patient Attitudes Toward Testicular Prosthesis Placement After Orchiectomy

Orchiectomy is the standard of care for many testicular conditions. Testicular prosthesis placement (TPP) can mitigate psychosocial burden, restore self-image, and improve quality of life for patients requiring orchiectomy. Limited data exist regarding patient attitudes and counseling on TPP in the United States. The objective of this study was to characterize patient experiences after TPP, rationale for pursuing/declining TPP, and satisfaction levels.

Patients with a history of urologic conditions warranting orchiectomy were identified and sent an anonymous survey addressing demographics, pre/post counseling, attitudes toward TPP, satisfaction rates, and postoperative complications. Sixteen percent (76/480) of patients completed the survey. Of these, 50.8% (32/63) undergoing orchiectomy were counseled by their surgeon about TPP, and 22.2% (14/63) received a prosthesis. The most common reasons for declining TPP included lack of concern for cosmetic appearance and lack of counseling. Leading reasons for pursuing TPP included improving self-confidence and cosmetic appearance. Although 71% (10/14) of patients were satisfied with TPP, they did highlight areas for improvement. Twenty percent (2/10) felt their implant was too high, 60% (6/10) felt their implant was too firm, 10% (1/10) endorsed discomfort during sex, and 30% (3/10) felt that TPP did not match their size expectations. Despite these findings, 71% (10/14) reported that they would have TPP again and 79% (11/14) would recommend TPP to others.

TPP improves body image and quality of life following orchiectomy. Provider counseling plays an important role in influencing a patient’s decision to undergo TPP. Areas of improvement include implant positioning and more effective replication of testicular consistency.
